# Frequency conversions

Every frequency unit on the site, and every conversion between them. Each page shows a full table, the exact formula and a live calculator.

## All frequency units

*Every frequency unit and its size relative to the base unit.*

| Unit | Symbol | In hertz |
| --- | --- | --- |
| hertz | Hz | 1 |
| kilohertz | kHz | 1,000 |
| megahertz | MHz | 1,000,000 |
| gigahertz | GHz | 1,000,000,000 |
| revolution per minute | rpm | 0.01666666667 |
